"Save current as" level and not losing bake light data


is there any way to “duplicate/saves as” a level without losing all the baked light data?

I just need a copy of the same level and would be great no to do the whole light bake again

thank you

and as always just answering myself

copy the entire project in another directory of your computer, open it and change the name of the level you want to duplicate, after that, migrate the level to your original project, leaving only selectet the level itself and its “map build data registry”

better solution,
1- copy both map and builtdata file to a new folder outside the project
2- rename the map file inside the project, then builtdata file will be renamed automatically by the engine
3- copy the original map and builtdata back to thier loction in the project
voila !!
